My minecraft has issues with processing image, exactly every 3 seconds. The game first runs normally but when 3rd second comes the game just lags a lot. (My specs. are more than enough to process Minecraft @ +60fps at all time). This started happening when I updated launcher from old one (lag spikes weren't happening previously but after updating launcher they do) and started playing on 1.14.4. NO MODS OR JAVA ARGUMENTS USED.
